TozZZ whom it may concern.:

e LEY,`a citizen of theUnited States, residing at Roslindale, inthe'countyof'Suifolk and State of Massachusetts, have invented certainnew and useful Improvements in Lubricating Devices; and I do herebydeclare the f ollowing to be a full, clear, and eXact description of theinvention such as will enable others skilled in thepa'rt to which itapper-y tains to make and use the same.

The present invention relates to lubricating devices for bearings, andmore particularly to that Class of devices in which a carrying memberlsuch asanroil rlng 1s employed for supplying lubricant to the bearingfrom a reservoir located beneath the same.

. One of the objects of the present invention is to improve theefficiency of the above type of lubricating devices l y increasing theamount of lub-ricant supplied to the bearing by the carrying member orring. Another object is to provide for a more efficient distribution ofthe lubricant throughout the bearing.' With these and other objects inView, as will hereinafter appear, the present invention consists in thedevices and combinations of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through the bearing; and Fig. 2 is a vertical transverse sectionon line 2 2, Fig. 1, looking in the direction of the arrows, Certainportions being omitted for clearness of illustration.

As shown in the drawings, the bearing sleeve 5 for the rotating shaft 6is cut away as 'shown at 7 to provide passage for the oilcarrying ringsor members which operate to transfer oil from the oil reservoir 8 to therotating shaft and bearing.

The oil rings are of'two sizes, a smaller ring 13 which rests upon theshaft at the top, Supporting in turn a larger ring 14, and both rings attheir lower portions dipping beneath the Surface of the oil in thereservoir. Preferably therings are formed with a groove 15 Von theirinner faces, and with a corresponding rib 16 on their outer faces, therib 16 of the smaller ring 13 entering the groove 15 of the larger ring14, thus maintaining the rings'in alinement.

It will be observed that by the employment of a pair of rings arrangedas above de- LUEEICATING DEVICE.

it known that I, OLIVER D'. H. BENT scribed a greatly increased supplyof lubricant is furnished to the bearing. Not only is the lubricantwhich is carried up by the inner surface of the inner ring 13transferred directly to the rotating shaft 6 as with Vthe ordinary formof o-il ring bearing, but the lubricant on the outer faceof the innerring" Patented May V27.19179.

13 and the inner face of the outer ring la is'A also supplied to thebearing, being squeezed out or thrown out laterally of the rings, thatis, axially ofthe-shaft andbearing as the rings come together at the topof thevbear-A ing. The groove, 15. in the outer ring 11 lis particularlyefficacious in raising the lubricant from the reservoir, and therib 16on the inner ring 13, as it enters the groove in the outer ring, forcesthe lubricant out of the groove and on to the flat faces of the ringsfrom which it is forcibly thrown out axially of the shaft and bearing tobe distributed along the same.

By providing a groove or channel 17 along the top of the bearing blockor sleeve 5 with oil holes or passages 18 leading from the bottom of thegroove tothe inner surface of the bearing, the latter will be kept welllubricated, even at considerable distances from the oil ring.

While in the drawings are shown a pair of coperating oil rings, it isevident that additional [rings may be used ifttan increased amount oflubricant is desired. By providing a plurality of rings of differentsizes l having a, glroove on their inner face, and a corresponding ribon their outer face, the

appropriate sizes and numbers of rings may be selected for any givenbearing.

Having thus described the present invention, what is claimed is:

1. The combination with the shaft of a bearing having an oil ringreceiving groove and an oil passage extending from the top of thebearing adjacent the groove to the bearing surface, an oil reservoir, anoil ring dipping into'the oil in the reservoir, and means for deliveringthe oil from the outer surface of the ring axially of the shaft into theoil passage.

2. The combination with the shaft and bearing sleeve having an oilreceiving Chan` nel in its upper Surface, of an oil reservoir,

an oil ring with its inner surface contact- Y ing with the top of theshaft, the ring dipping into the oil in the reservoir, and means inrolling Contact with the outer surface of the ring'atrthe top thereoffor deliveringl the oil from said surface axially of the bearing intothe oil receiving channel. l

3. The combi ationV With the shaft of'a bearing having an oil ringreceiving groove and an oil passage extending from the top of thebearing adjacent the groove to the bearing surface, an oil reservoir7oil rings of different diameters eccentri cally arranged one Within theother, said rings ldipping into the oil in the reservoir and havingsubstantially cylindrical contacting surfaces adjacent the ends of therings to force the` oil latorally from between the rings. i

4. The combination With the shaft 'and bearing sleeve, of an oilreservoir, and a pair o f oil-carrying members driven from the shaft andcontacting with the oil in the reservoir, said members cooperating todeliver oil axially of the shaft to the outside-of the bearing sleeve atthe top. 5. The Combination With theV shaft and bearing, of a reservoir,and apair of oil rings of different diameters eccentrically arbearing,of an oil reservoir,` anda pair of oil rings of diiferent diameterseccentrically arranged one Within the other, in contact at their top andsepa-rated at their bottom, said rings being provided With a coperatingrib and groove on their contacting faces.

7. The combination with the shaft and bearing, of an oil/reservoir,v andan oil ring With its inner surface contacting with vthev top ofthe'shaft, the ring dipping both its inner and outer surfaces'into theoil in the reservoir and arranged to deliver oil from its inner surfacetothe portions of the bear-i ing nearer the ring-and means coperatingwith the ring for delivering oil from Yits outer surface to the portionsof the hearing farther from the ring.
